I just repaired a stuck eject mechanism on a 512k, and used my go-to lubricant... schaeffer's penetro 90. It breaks down the old grease, and leaves lubrication behind unlike wd-40. Someone had removed a disk from the drive forcefully, and broke the plastic piece that moves into the optical sensor to tell the drive when the disk is installed. To fix it I heated up a piece of wire with a torch and melted it into the plastic. After trimming to length it works perfectly. -J On Fri, Apr 29, 2016 at 12:01 PM, william degnan via vcf-midatlantic <vcf-midatlantic@lists.vintagecomputerfederation.org> wrote:
Just an FYI, these two books : Dead Mac Scrolls ( http://www.amazon.com/Dead-Mac-Scrolls-MacIntosh-Thousands/dp/0940235250) and Mac Classic & Se: Repair and Upgrade Secrets ( http://www.amazon.com/Mac-Classic-Se-Upgrade-Secrets/dp/1566090229) Are extremely useful books for this type of repair. I use them both a lot on all of the unibody Macs that I'm fixing.
Details on what parts drive what in ways that are fairly simple to understand (I just need the guidance as to what part to replace as well... not an EE... I can solder well enough for any sort of repair on these :-) )
I've also got some things for stuck drives (and sources for the gear that can go as well).

Thank you very much. I am also interested in more information about repairing stuck drives.
